String is super set-in-and-forget-it in nature. We don't ever really have to worry about it working - it just works, and actively saves us money on a daily basis. What's particularly cool is that it's dynamic. As rate cards shift, the algorithm immediately adapts.

String has not only allowed us to take full advantage of our current parcel rate structures but has also helped us improve them. We have parcel carriers now fighting for our business while we are enjoying lowered order processing times!

Customer Case Study

String Found Savings Of $7.50 Per Shipment On Average.

Before using String we were shipping everything out on USPS and FedEx, using String we found that using UPS for the majority or our shipments would save us on average $7.50 per shipment. I would recommend using String to anybody looking to optimize profits in their business and looking to lower their shipping costs.

Frequenty Asked Questions

 

How Does String Help If I Already Have Shipping Rules?

Your ShipStation rules might work 60-70% of the time, but when they're wrong, it costs you money. Your team doesn't have time to check every order and find the best rate manually. That's where String comes in! String knows your products, package sizes, and carrier options. When a new order comes in, we automatically pick the best option in real time. Instead of being right only 70% of the time, you now get the best rate 100% of the time—saving you money on every shipment!

Will String Only Pick Slow USPS Services?

No! String is built to get your orders to customers fast while also saving you money. String checks delivery times for every shipment. If a shipping option won't arrive on time, String filters it out automatically. This means you get the best rate without slowing down delivery—and sometimes, even faster shipping!

How Does String Pick the Smallest Package?

String finds the smallest and best box for every order. We keep track of all your products' sizes and weights and test different ways to fit them into the smallest box possible. If a product needs special packing, no problem! String follows your rules to make sure everything is packed just right. Need to add new products or packages? It's easy! No matter how many items you have, String will always find the best fit to save you money.

Do I need to change my shipping setup?

No! String integrates seamlessly with ShipStation—no changes needed, just savings.
